Packages 14 wrapped in a heat-shrinkable film are conveyed along rails 11, 12, 13 by endless belts 17, 22 arranged on rollers 18, 19, 21 and 23, 24, 25 respectively in such a way that the packages 14 are compressed in moving along the rails. In the compressed state, the packages 14 are subjected to heat treatment by hot air distributers (26, 27), Fig. 2 (not shown), arranged above and below the conveyer system, and the film is caused to shrink tightly about the packages 14, thereby holding them in compressed form. The film may be heatsealed simultaneously with the shrinking process. In a modification, Figs. 4-6 (not shown), the compression and heat-shrinking stages of the process are carried out at the same time using radiant heat. In a further modification, Figs. 7-10 (not shown), packages are mounted on an open-ended tray, the whole being wrapped in a heat-shrinkable film. Compression of the packages and shrinking of the film may be effected either successively or simultaneously.

Book-stitching machines.-Fastened signatures are supported upon a book-table 20, Fig. 5, provided with feed-bars 25 by which the pile of signatures is positively moved to the left after each fresh signature is secured. The bars 25 are reciprocated by cam-actuated levers 22, are pressed upward by springs and are caused to rise above the level of the table on the leftward stroke by means of pins 30 on the bars which ride up and over inclined guides 28. A support 42, 43 slides freely upon the table and when the table is full is used to trip the stop-gear of the machine. The book-table 20 is carried by a vertical screw 33, Fig. 1, by which and handgear 34, 36, 37, the table can be raised and lowered. Starting and stopping gear.-The machine is driven from a shaft 2, gear-wheels 4, 5, and grooved friction pulleys 8, 10. The pulley 8, with the gear-wheel 5 are mounted at the end of a treadle-lever 9 and the friction-wheels are brought into contact by depressing the treadle. A link 55 is guided in a slot in a stationary arm 50 and is moved to the right by a cam 57 when a stopping rod 68 and a stopping lever 52<1> are moved to the right. In this movement, a cam notch in the rod 55 engages a pin 56<1> in the arm 50 and, thereby, the rod 55 is lifted sufficient to lower the pulley 8 out of contact with the pulley 10. When the work-table is full, a pin 59 on the support 43 engages and lifts a latch 60 so as to release a lever 61. The latter is then turned by a spring 63 and, engaging a lug upon the lever 66 turns it and actuates the stopping rod 68. When the machine is at rest, it may be turned by means of a hand-wheel 70 and a grooved friction pulley 13.

Title: Improvements in electric motor control systems
IPC: B60L15/00
Filed: 1935-12-10
Abstract: 466,819. Master control of D.C. motors. GENERAL ELECTRIC CO., Ltd., CROFT, E. H., and PYE, J. F. Dec. 10, 1935, No. 34193. [Class 38 (iii)] In a series-parallel control system, provision is made for effecting a series connection of the motors, a parallel connection, a connection in which the parallel circuits are completed independently of series control resistances and their control switching means, and a parallel connection in which the resistances serve for field weakening, the several circuit connections of the motors being effected by two two-position switch groups adapted to be relatively positioned in like and unlike positions, and two of the circuit connections including contacts of the two groups series-connected. When a master controller is moved to a first series position lines switches LS1, LS2, close, and, the two two-position switch groups being in their " off positions the contacts S1A, S1B, are closed, so that the motors 1, 2, are connected in series across the supply in series with respective armature resistances 9, 10. Contacts 11-14 are then closed in steps to cut out the resistances 9, 10 in steps under the control of a current limit relay 58 and, at the completion of this stage, a series contactor S2 is closed to cut out terminal portions 60, 61, of the resistances 9, 10, and exclude the resistances independently of the contacts 11-44. When the master controller is moved to a full parallel position the contacts 11-44 are opened and one of the two two-position switch groups is operated to its " on " position. Contacts S1A, F1A, F2A, are thereby opened and contacts P1A, P2A, closed. The series contactor S2 then opens and the motors 1, 2, are connected in parallel across the supply each in series with its armature resistance 9, 10. The contacts 11-44 again close to remove the resistances 9, 10, in steps and the other of the two two-position switch groups then operates to open contacts S1B and close contacts P3B, P4B, F1B, F2B. The contacts P3B, P4B, bridge resistances 9, 10 and the contacts P1A, P2A. The contacts 11-44 again open and, when the master controller is moved to a first weak field position the first-operated of the two two-position switch group returns to its " off " position to open contacts P1A, P2A, and close contacts F1A, F2A, S1A. Thus the resistances 9, 10 are connected each in series with a resistance 45 or 46, across the field 3 or 4 of its respective motor. In the weak field position of the master controller the contacts 11-44 are again closed under control of the current limit relay to remove the resistances 9, 10, in steps. A trip coil may be provided for effecting operation of an overload relay which controls the line switches LS1, LS2, and a normally open contact of the overload relay may control a test relay whereby the various switch groups may be tested as described in Specification 466,285.

Title: Drag shoe devices for vehicles
IPC: B60T1/14
Filed: 1932-12-07
Abstract: 411,176. Skid brakes. BORJYNSKY, T. M. VON, 32, Rue de Boulainvilliers, Paris. Dec. 7, 1932, No. 34662. [Class 103 (i).] In a vehicle brake comprising a brake shoe adapted to be lowered into engagement between the wheel and the track power-actuated means for raising the shoe is provided. The power means may be an electric motor or the running axle of the vehicle and may be automatically rendered inoperative when the shoe has been raised to a predetermined position. In Figs. 1, 3 and 3<a>, the shoe 1 is mounted upon an arm 2 pivoted upon the wheel axle 7 and is retained in the raised position by a spring catch 27, 28 of which the element 27 is pivoted on a fixed bracket 20 and carries the armature of a magnet 23. The hub 6 of the arm 2 forms one member of a ball ratchet-clutch the other member 10 of which is slidably keyed on the axle 7. The balls 9 are normally out of alignment with the projections 8 so that the clutch is inoperative in both directions of rotation of the axle. By momentarily energizing the magnet 23, the shoe 1 drops into operative position and the movement of the catch member 27 towards the bracket 20 effected by the spring 24, after disengagement of the shoe, slides the clutch member 10 through connections 17 and the fork 13 to bring the balls 9 into the effective position shown in Fig. 3<a>. Upon reversing the movement of the vehicle the axle then raises the shoe until the outward movement of the catch member 27 as it is engaged by the member 28 returns the clutch 10 to the inoperative position. In another arrangement, Fig. 5, the shoe 1 is raised by a cable 29 winding on a drum 30 geared to an electric motor 33, the circuit of which includes, in addition to the hand switch 37, a switch 39, 40, the member 40 of which slides in brackets 43, 45. The shoe may be retained in the raised position by a detent which can be released to allow the shoe to fall and it is raised upon closing the switch 37 until a projection 50 on the drum 30 engages a rod 47 contacting a projection 45 on the switch member 40 which is thus moved to break the circuit. Specification 411,175 is referred to. Reference has been directed by the Comptroller to Specifications 15435/90, 13863/91, 15362/92, [all in Class 108], and 17800/07, [Class 103].

Abstract: 333,472. Semet-Solvay Engineering Corporation, (Assignees of Steere, F. W.). Nov. 17, 1928, [Convention date]. Producers.-In the recovery of waste heat from industrial gases, in particular from water gas plants, the gases are passed into a flash boiler, the steam from which is delivered to a heat conserving body of water. In the application to a water gas set comprising a generator 5, carburettor 6, and superheater 7 the " blow " gases pass to the flash boiler 10, which consists of a number of heat absorbing surfaces 11, and escape at an outlet 12. At the commencement of the " run," gas is diverted from the boiler and simultaneously water is sprayed from nozzles 15 on to the heated surfaces. The steam is conveyed through pipe 16 to the distributor 17 within the heat transformer 19, perforations in the bottom of the distributor being below the constant water level of the transformer. Steam from the latter passes to the generator and surplus hot water is pumped to the sprayers 15 to be heated again. Unvaporized water in the boiler is conveyed by pipe 30 for recirculation. If the water gas set is operated in two cycles, including an " up-run " and a " back-run," the latter may follow the " up-run " while water is still being supplied to the boiler.
